SNMP-REPEATER-MIB Table View

Table of descriptive and status information about
the groups of ports.

Table of descriptive and status information about
the repeater ports in the system.  The number of
entries is independent of the number of repeaters
in the managed system.

A table of information about each
non-trivial repeater. The number of entries
depends on the physical configuration of the
managed system.

Table of performance and error statistics for the
ports.  The number of entries is the same as that
          
in the rptrPortTable.
          
The columnar object rptrMonitorPortLastChange
is used to indicate possible discontinuities
of counter type columnar objects in the table.

Table of additional performance and error
statistics for 100Mb/s ports, above and
beyond those parameters that apply to both
10 and 100Mbps ports.  Entries exist only for
ports attached to 100Mbps repeaters.
          
The columnar object rptrMonitorPortLastChange
is used to indicate possible discontinuities
of counter type columnar objects in this table.

A table of information about each
non-trivial repeater.  The number of entries
in this table is the same as the number of
entries in the rptrInfoTable.
          
The columnar object rptrInfoLastChange is
used to indicate possible discontinuities of
counter type columnar objects in this table.

A table of additional information about each
100Mb/s repeater, augmenting the entries in
the rptrMonTable.  Entries exist in this table
only for 100Mb/s repeaters.
          
The columnar object rptrInfoLastChange is
used to indicate possible discontinuities of
counter type columnar objects in this table.

This table contains one entry per repeater in the
system.  It defines objects which allow a network
management application to instruct an agent to watch
for a given MAC address and report which port it
was seen on.  Only one address search can be in
progress on each repeater at any one time.  Before
starting an address search, a management application
should obtain 'ownership' of the entry in
rptrAddrSearchTable for the repeater that is to
perform the search.  This is accomplished with the
rptrAddrSearchLock and rptrAddrSearchStatus as
follows:
          
try_again:
    get(rptrAddrSearchLock, rptrAddrSearchStatus)
    while (rptrAddrSearchStatus != notInUse)
    {
        /* Loop waiting for objects to be available*/
        short delay
        get(rptrAddrSearchLock, rptrAddrSearchStatus)
    }
          
    /* Try to claim map objects */
    lock_value = rptrAddrSearchLock
    if ( set(rptrAddrSearchLock = lock_value,
             rptrAddrSearchStatus = inUse,
             rptrAddrSearchOwner = 'my-IP-address)
          == FAILURE)
        /* Another manager got the lock */
        goto try_again
          
    /* I have the lock */
    set (rptrAddrSearchAddress = <search target>)
          
    wait for rptrAddrSearchState to change from none
          
    if (rptrAddrSearchState == single)
        get (rptrAddrSearchGroup, rptrAddrSearchPort)
          
    /* release the lock, making sure not to overwrite
       anyone else's lock */
    set (rptrAddrSearchLock = lock_value+1,
         rptrAddrSearchStatus = notInUse,
         rptrAddrSearchOwner = '')
          
A management station first retrieves the values of
the appropriate instances of the rptrAddrSearchLock
and rptrAddrSearchStatus objects, periodically
repeating the retrieval if necessary, until the value
of rptrAddrSearchStatus is 'notInUse'.  The
management station then tries to set the same
instance of the rptrAddrSearchLock object to the
value it just retrieved, the same instance of the
rptrAddrSearchStatus object to 'inUse', and the
corresponding instance of rptrAddrSearchOwner to a
value indicating itself.  If the set operation
succeeds, then the management station has obtained
ownership of the rptrAddrSearchEntry, and the value
of rptrAddrSearchLock is incremented by the agent (as
per the semantics of TestAndIncr).  Failure of the
set operation indicates that some other manager has
obtained ownership of the rptrAddrSearchEntry.
          
Once ownership is obtained, the management station
can proceed with the search operation.  Note that the
agent will reset rptrAddrSearchStatus to 'notInUse'
if it has been in the 'inUse' state for an abnormally
long period of time, to prevent a misbehaving manager
from permanently locking the entry.  It is suggested
that this timeout period be between one and five
minutes.
          
When the management station has completed its search
operation, it should free the entry by setting
the instance of the rptrAddrSearchLock object to the
previous value + 1, the instance of the
rptrAddrSearchStatus to 'notInUse', and the instance
of rptrAddrSearchOwner to a zero length string.  This
is done to prevent overwriting another station's
lock.

Table of address mapping information about the
ports.

A table to extend the address tracking table (i.e.,
rptrAddrTrackTable) with a list of source MAC
addresses that were recently received on each port.
The number of ports is the same as the number
of entries in table rptrPortTable. The number of
entries in this table depends on the agent/repeater
implementation and the number of different
addresses received on each port.
          
The first entry for each port contains
the same MAC address that is given by the
rptrAddrTrackNewLastSrcAddress for that port.
          
Entries in this table for a particular port are
retained when that port is switched from one
repeater to another.
          
The ordering of MAC addresses listed for a
particular port is implementation dependent.

A table of control records for reports on the top `N'
ports for the rate of a selected counter. The number
of entries depends on the configuration of the agent.
The maximum number of entries is implementation
dependent.

A table of reports for the top `N' ports based on
setting of associated control table entries. The
maximum number of entries depends on the number
of entries in table rptrTopNPortControlTable and
the value of object rptrTopNPortGrantedSize for
each entry.
          
For each entry in the rptrTopNPortControlTable,
repeater ports with the highest value of
rptrTopNPortRate shall be placed in this table
in decreasing order of that rate until there is
no more room or until there are no more ports.
